T 0 all whom it may concern:

Be it known that I, CLARENCE I. HoLLls- TER, a citizen of the United States, residing at Pittslield, in the county of Berkshire and State of Massachusetts, have invented an Improvement in intake Devices for Explosive Mixtures in Vapor-Engines, of which the following is a specificatio Difliculties have heretofore repeatedly been experienced in multiple cylinder vapor mixture engines from the failure of the vapor mixture intakes and the cylinders supplying the mixture in equal volumes and with equal rapidity, and the object of my invention is to overcome this difliculty.

The device of my invention applies especially to a six cylinder vapor engine and comprises a structure which arranges the six cylinders in three intake groups of two each, all of which latter are supplied with the vapor mixture from a common source. This common source is supplied from a general source divided equally into the common-source and the general source is centrally supplied by a single pipe. In this manner the volume of explosive mixture from the single pipe is equally divided and then equally sub-divided and then equally re-sub-divided into the direct intake pipes of all-the six cylinders,all of which is hereinafter more fully expressed.

In the drawing, Figure 1 is a plan and partial central section through the device of my improvement. Fig. 2 is a cross section at the dotted line 90, ac, of Fig. 1, and Fig. 3 is a gross section through the dotted line y, y, of

A general source or chamber Z at its respective ends and by intakes 1 opens into and communicates with the continuous chamber or common source It at points that are substantially midway between the intakes g and h and h and '11. A single pipe m supplies the explosive mixture directly into the center of the general source or chamber Z.

scription, it will be apparent that the volume of explosive mixture entering through the pipe m. into the general source or chamber l is equally divided into the common equally sub-divided at the center and ends of the chamber is and through the three intakes g h and i into the chambers g h and 'i, and is then equally re-sub-divided into the throats a b c d and f 1 connecting with the intake pipes to the respective six cylinders; hence each of the six cylinders will be supplied as explosive mixture. A proper and perfect working of the said six cylinders is substantially impossible unless an equal volume of explosive mixture is supplied thereto.

I claim as my invention 2- 1. A vapor mixture intake device for a six cylinder engine comprising three intake groups of two each, a single intake to each group, a continuous chamber into which the several single intakes open, a general chamber connecting at its respective ends with the said continuous chamber and a single pipe tqonnecting centrally with the general cham- 2.
